I have put about 150 miles on the sled so far and it rips... It runs perfect and i love the setup but i i can't get the skis up in the air anything like i could with my F7. I have a 136 track with a 4 inch setback, the same setup i had on my f7 and i could hang the skis all day long with my f7... The way i like it.... Now with this sled, it seems like i'm not getting nearly enough weight transfer. The sled spins like a mofo and i think that with alittle more weight transfer i think my spinning problem will be solved... I had my F7 skid setup exactly the way i liked it, but i'm having alittle more problem setting up the new sled... Any help would be great... How in the hell are the mods able to stand em up, but i can't?!
